LEADER-PIPE STRAP.

Application filed June 11, 1926. Serial No. 115,240.

This invention relates to straps or hands for attaching water conductoror leaderpipes to the walls of buildings. Such leader-pipes are customarily supported by placing-the sides thereof between the arms of a U-shaped staple, havin a central prong adapted to be driven into t e wall. A wire attached to the outer ends of the staple arms and spannin the front surface of the leader In pipe holds t e latter in its positlon 1n the staple. In order to conceal the staple and wire, ametal band which embraces the front.

and sides of the leader-pipe is. then placed over the fastenin ,"ornamental ends being I soldered to the and, which is in turn soldered to the leader-pipe. Leader-pipes are frequently formed of corrugated metal, such as copper; and these corru ations render it diflicult to pro erly solder the flat metal band thereto.

joints are always more or less unslghtl This method of installation is further 0 jectionable by reason of the labor expense involved.

An object of the present invention is to provide a one-piece leader-pipe strap of simple construction which may be rapidly and economically stamped from sheet metal, and which will, when installed, present an 3 attractive appearance. A further ob ect of the invention is the provision of such a stra of a construction sufficiently strong and rigi so that it will adequately sup ort the leader-pipe without the use of a le er-pipe' staple. A further object of the invention is the provision of such straps of a construc;

tion to permit of their being closel nested, in order to minimize shipping an storage space andpreclude damage in handling.

A further object is the provision of such straps so designed and constructed that,

when delivered nested to the location where they are to be installed, the? may be readily bent, by unskilled labor an wlthout the employment of toolsor fixtures, to accurately I conform to the contour of the leader-pipe which they are to support. A, further object is the provision of such a strap which may be installed by the mere driving of two nails or screws. Other advantageous features of the invention will be apparent from the specification and drawings.

In the accompanying drawings:.

Like reference characters indicate like parts throughout the drawings. I

In the illustrated embodiment of themvention, a strap 1, stamped from sheet metal, is provided with embossed-ornamental ends, 2 and 3. Intermediate such ends are embossed front reinforcing ribs 4 and 4, and embossed reinforcing side ribs 5 and 5 and 6 and 6. Between embossed end 2 and the adjacent ends of side reinforcing ribs 5 and 5 is provided a flat bending z0ne, 7, A similar bending zone, 8, is provided between the opposite ends of side reinforcing ribs 5 and 5 and the adjacent ends'of front reinforcing ribs 4 and 4'; another such bending zone 9 is provided betweenthe opposite ends of front reinforcin ribs 4 and 4 and the adjacent ends of si e reinforcing ribs 6 and 6*; and a fourth such bending zone 10 is provided between the opposite ends of side reinforcing ribs -6 and 6 and the adjacent embossed end 3. 105

The functions of these reinforcing ribs are to give strength and rigidity to the front and. side-walls of the strap, to insure that said walls shall remain straight, to define the bending zones, and to give the strap a such comprising the respective bending zones can be readily brought to the required shape to conform to the corners of the leader-pipe, whatever the contour of such corners may be. Furthermore, the flat bending zones adjacent the embossed ends permit of deflecting the inner edges of such ends out of parallelism with the plane of the front su'rface of the strap, to meet the condition where the strap is to be attached to an irregular surface, such as the inclined surface of a clapboard.

Referring to Fig. 6: By bending the strap at angles which are obtusewith reference to the side walls of the leader-pipe, the driving of the fastening nails or screws (which pass through holes in the straps and into the wall of the building) forces the embossed endsv 2 and 3 into close contact with the wall surface. These ends bein inherently very rigid because of their em ossing, they cannot readily be bent away'from' the wall surface by accident, once they are forced into contact with such surface.

7 It will be apparent that straps embodying the invention may be readily formed from sheet metal by a single stroke of a stampin pressthus permitting of their economica manufacture. It will be understood that sheet metal is to be employed which is of sufficient thickness and strength to ade quately clamp andv support the leader pipe in its position on the wall surface.

I claim:

1. A leader-pipe supporting strap comprisin a single strip of sheet metal consisting 0 end portions having embossed reinforcements and a front portion between said end portions and having embossed reinforcement, said front embossed portion being spaced from the endembos'sed portions to form flat bending zones between said front and end portions. p

2. A leader-pipe supporting strap comprising a sing e strip of metal provided with a front wall having a reinforcement embossed therein, side walls having reinforcements embossed therein, and projectin ends havin reinforcements emboss'e therein, said ront, sideand end portions being spaced from each other to form flat transverse bendin zones therebetween.
